JOHN SMITH NORRIS, OF RED LODGE, MONTANA.

WH EEL-CU LTIVATOR.

SPECIFICATION forming part of Letters Patent No. 636,167, dated October 31, 1899 Application filed March 1,1899. Serial No. 707,370. (No model.)

To all whom it may concern:

Be it known that 1, JOHN SMITH NoRRIs, a citizen of the United States, residing at Red Lodge, in the county of Carbon and State of Montana, have invented certain new and useful Improvements in Wheel-Cultivators, of which the following is a specification.

My invention relates to wheel-cultivators, and has for its object to provide a cultivator in which the workman will have his work before him and in which the frame carrying the operative parts and each of the operative parts are adjustable. This object I accomplish in the manner and by the means hereinafter more fully described in detail and particularly pointed out in the claims, reference being bad to the accompanying drawings, in which like reference-letters indicate like parts in all the figures.

Figure 1 is a top plan View of my invention. Fig. 2 is a side elevation of same. Fig. 3 is a front elevation of same.

My invention consists of a frame A, formed of three arches a, with a small space a between the middle arch a and each of the side arches a. The spaces a. are closed top and bottom. Links B, provided at each end with a gudgeon b, are placed one in each space a,

the gudgeons b pivoted in the top and bottom of said spaces a. Passing through each of said links B, from rear to front, are two levers 0, one near the top of said link Band the other near the bottom. The said levers C are pivotally secured in said links B. The forward ends of each pair of levers O are pivotally secured in shorter links 0, one near the top of said link 0 and the other near the bottom. To the under side of each lowerlever 0, between the links B and '0, a bar D is secured diagonally across the lever O by a clip d, admitting of adjustment along the lever G. Cultivator-teeth E, of any desired kind provided with shanks, may be attached to the bar D by nuts e or other suitable device admitting of vertical adjustment. If desired, instead of the bar D and the cultivator-teeth E,- a frame may be swung to the forward ends of the two lower levers O and a stirring-plow attached to the center of said frame. The frame A is mounted between two upright standards F, so as to be vertically adjustable, and said standards F have projecting outward from their centers spindles f, on which wheels f are placed. A seat-bar G is secured to the center of the crown of the middle arch a and extends to the front and rear. Curved braces g extend from the rear end of the seat-bar G to the lower ends of the standards F over the levers O, and braces H extend from the lower ends of the standards F to the seat-bar G, forward of said levers O. A seat I is placed on said seat-bar G in any of the usual ways and a tongue J attached to the front end of said seat-bar G by clamps admitting of adjustment. An ordinary doubletree is placed on said tongue J and singletrees attached to it.

The operation of myinvention is as follows: The frame A being secured at the proper height on the standards F, the cultivatorteeth E being adjusted at the proper height, and the bars D sufficiently far apart to permit the 'row of plants to pass between the center teeth, the workman mounts to his seatand as the cultivator moves along raises or lowers or moves from or to the row the cultivator-teeth E by means either of his hands operating the upper levers O or his feet the lower levers G, in either case the pair of levers 0, upper and lower, moving together.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a wheel-cultivator, a vertically-adj ustable frame consisting of three arches, the middle arch having a small space between it and each of the side arches; two levers hung one above the other in each of said spaces and adapted to move horizontally and vertically, said levers having their forward ends connected together; and cultivator-teeth attached to the forward ends of each of said lower levers, substantially as shown and de-. scribed.

2. In a wheel-cultivator, a vertically-adjustable frame consisting of three arches, the middle arch having a small space between it and each of the side arches; a link provided with a gudgeon at top and bottom, said gudgeons pivoted in the tops and bottoms of said spaces, a pair of levers extending through each of said links from rear to front and pivoted vertically in said links, the forward ends of each pair oflevers connected together; and cultivator-teeth attached to the forward ends of each of said lower levers, substantially as shown and described.

In a wheel-cultivator having a verticallyadjustable frame consisting of three arches, the middle arch separated from each of the side arches by a small space, said space closed at top and bottom,-two pairs of levers, loosely connected at their forward ends, and cultivator-teeth attached to said forward ends, a link in each of said spaces, said link provided at top and bottom with gudgeons pivoted in the top and bottom of said spaces, substantially as shown and described.

4. A wheel-cultivator, consisting of a frame having three arches with a small space between the middle and each of the side arches, said spaces closed at top and bottom, said frame adjustably mounted between two upright standards, two upright standards provided with spindles and mounted on wheels,

a link with gudgeons at the top and bottom, pivotally mounted in each of said spaces, a pair of levers passing through said link and pivotally mounted therein, the forward ends of said levers loosely joined together, culti- JOHN SMITH NORRIS.
